Our Lady's 15 Promises for Praying the Rosary

Besides the Indulgences attached to the Rosary, Our Lady revealed to St.
Dominic and Blessed Alan de la Roche additional benefits for those who devoutly pray the Rosary.
Our Lady's promise is shown in darker blue text.
Additional explanation on and doctrinal connections to each promise is shown following in the smaller
normal text font and color. Note that the Rosary is the prayer
(non-Liturgical) with the most published Magisterial / Papal documents
expounding on its excellence. Vatican II's summary on Our Lady is contained in Lumen
Gentium chapter VIII.

Signal Graces are those special and unique Graces to
help sanctify us in our state in life. See the remaining promises for an
explanation for which these will consist. St. Louis de Montfort states
emphatically that the best and fastest way to union with Our Lord is via
Our Lady [True Devotion to Mary,
chapter four].

2.

I promise my special protection and the greatest graces to all those who
shall recite the Rosary.

Our Lady is our Advocate and the channel of all God's
Grace to us. Our Lady is simply highlighting that She will watch
especially over us who pray the Rosary. (see Lumen
Gentium chapter VIII - Our Lady #62) [a great more detail is available
on this topic in True Devotion to Mary, chapter four, by St. Louis de Montfort]

3.

The Rosary shall be a powerful armor against hell, it will destroy vice,
decrease sin and defeat heresies.

This promise, along with the next, is simply the
reminder on how fervent prayer will help us all grow in holiness by
avoiding sin, especially a prayer with the excellence of the Rosary. An
increase in holiness necessarily requires a reduction in sin, vice,
and doctrinal errors (heresies). If only the Modernists could be convinced
to pray the Rosary! (see Lumen
Gentium chapter V - The Call to Holiness #42) St. Louis de Montfort
states "Since Mary alone crushed all heresies, as we are told by the
Church under the guidance of the Holy Spirit (Office of the Blessed Virgin
Mary)..." [True Devotion to Mary #167]

4.

It will cause good works to flourish; it will obtain for souls the
abundant mercy of God; it will withdraw the hearts of men from the love of
the world and its vanities, and will lift them to the desire for Eternal
Things. Oh, that souls would sanctify themselves by this means.

The soul which recommends itself to me by the recitation of the Rosary
shall not perish.

Since Our Lady is our Mother and Advocate, She always
assists those who call on Her implicitly by praying the Rosary. The Church
reminds us of this in the Memorare prayer,
"... never was it known that anyone who fled to your protection,
implored your help or sought your intercession, was left unaided ..."

6.

Whosoever shall recite the Rosary devoutly, applying himself to the
consideration of its Sacred Mysteries shall never be conquered by
misfortune. God will not chastise him in His justice, he shall not perish by
an unprovided death; if he be just he shall remain in the grace of God, and
become worthy of Eternal Life.

This promise highlights the magnitude of Graces that the
Rosary brings to whomever prays it. One will draw down God's Mercy rather
than His Justice and will have a final chance to repent (see promise #7).
One will not be conquered by misfortune means that Our Lady will obtain
for the person sufficient Graces to handle said misfortune (i.e. carry the
Crosses allowed by God) without falling into despair. As Sacred Scripture
tells us, "For my yoke is sweet and my burden light." (Matthew
11:30)

7.

Whoever shall have a true devotion for the Rosary shall not die without
the Sacraments of the Church.

This promise highlights the benefits of obtaining the
most possible Graces at the hour of death via the Sacraments of
Confession, Eucharist, and Extreme Unction (Anointing of the Sick). Being
properly disposed while receiving these Sacraments near death ensures
one's salvation (although perhaps with a detour through Purgatory) since a
final repentance is possible.

8.

Those who are faithful to recite the Rosary shall have during their life
and at their death the Light of God and the plenitude of His Graces; at the
moment of death they shall participate in the Merits of the Saints in
Paradise.

Our Lady highlights the great quantity of Graces obtain
through praying the Rosary, which assist us during life and at the moment
of death. The merits of the Saints are the gift of God's rewards to those
persons who responded to His Grace that they
obtained during life, and so Our Lady indicates that She will provide a
share of that to us at death. With this promise and #7
above, Our Lady is providing the means for the person to have a very holy
death.

9.

I shall deliver from purgatory those who have been devoted to the Rosary.

Should one require Purgatorial cleansing after death,
Our Lady will make a special effort to obtain our release from Purgatory
through Her intercession as Advocate.

10.

The faithful children of the Rosary shall merit a high degree of Glory in
Heaven.

This promise is a logical consequence of promises #3 and
#4 since anyone who truly lives a holier life on earth will obtain a
higher place in Heaven. The closer one is to God while living on earth,
the close that person is to Him also in Heaven. The Catechism
of the Catholic Church states "Spiritual progress tends toward ever more
union with Christ." (Catechism
of the Catholic Church paragraph 2014)

11.

You shall obtain all you ask of me by recitation of the Rosary.

This promise emphasizes Our Lady's role as our Advocate
and Mediatrix of all Graces. Of course, all requests are subject to God's
Most Perfect Will. God will always grant our request if it is beneficial
for our soul, and Our Lady will only intercede for us when our request is
good for our salvation. (see Lumen
Gentium chapter VIII - Our Lady #62)

12.

All those who propagate the Holy Rosary shall be aided by
me in their
necessities.

If one promotes the praying of the Rosary, Our Lady
emphasizes Her Maternal care for us by obtaining many Graces (i.e.
spiritual necessities) and also material necessities (neither excess nor
luxury), all subject to the Will of God of course.

13.

I have obtained from my Divine Son that all the advocates of the Rosary
shall have for intercessors the entire Celestial Court during their life and
at the hour of death.

Since Our Lady is our Advocate, She brings us additional
assistance during our life and at our death from all the saints in Heaven
(the Communion of Saints). See paragraphs 954 through 959 in the Catechism
of the Catholic Church.

14.

All who recite the Rosary are my Sons, and brothers of
my Only Son Jesus
Christ.

Since the Rosary is a most excellent prayer focused on
Jesus and His Life and activities in salvation history, it brings us closer to Our
Lord and Our Lady. Doctrinally, Our Lady is our Mother and Jesus is our
Eldest Brother, besides being our God. (see Lumen
Gentium chapter VIII - Our Lady #62)

15.

Devotion to my Rosary is a great sign of predestination.

Predestination in this context means that, by the sign
which is present to a person from the action of devoutly praying the
Rosary, God has pre-ordained your
salvation. Absolute certainty of salvation can only be truly known if God
reveals it to a person because, although we are given sufficient Grace
during life, our salvation depends upon our response to said Grace. (See Summa
Theologica, Question 23 for a detailed theological explanation). Said
another way, if God has guaranteed a person's salvation but has not
revealed it to Him, God would want that person to pray the Rosary because
of all the benefits and Graces obtained. Therefore the person gets a hint
by devotion to the Rosary. This is not to say that praying the Rosary
guarantees salvation - by no means. In
looking at promises #3 and #4 above, praying the Rosary helps one to live a holy life,
which is itself a great
sign that a soul is on the road to salvation. (See also paragraphs 381,
488, 600, 2782 in the Catechism of
the Catholic Church.) In fact, St. Louis de Montfort says even more
strongly that "an infallible and unmistakable sign by which we can
distinguish a heretic, a man of false doctrine, an enemy of God, from one
of God's true friends is that the hardened sinner and heretic show nothing
but contempt and indifference to Our Lady..." [True Devotion to Mary, #30]

Reminder: these promises mean that, by faithfully and devoutly praying
the Rosary, Our Lady will obtain for us the
necessary Graces
to obtain said promises. It is still up to each individual soul to respond
to those Graces in order to obtain salvation.
